SPECIFICATION forming part of Letters Patent Nc.371,456, dated October11,1887.

Application tiled April 13, 1887. Serial Xo. 234,001.

To @ZZ whom it may concern.-

Be it known that LRICHARD M. Hnatuairen, a citizen of the United States,residing at Poughkeepsie, in the county ot' Dutchess and State of NewYork, have invented certain newr and useful Improvements in Stove Dainpers, of which the following is a specification, reference being hadtherein to the accompanying drawings.

This invention relates to thatclass of damp ers which retard, but do notprevent, the tiow through a pipe or tine; and ithas for its object tofacilitate and cheapen the manufacture of the damper, as well as improveits operation.

To this end the invention consistsin certain novel features ofconstruction, which will be fully understood from the followingdescription when taken in connection with the annexed drawings.

In the drawings, Figure l is a longitudinal sect-ion of a portion of a.pipe with the dain per, shown in perspective, attached thereto. Fig. 2is a plan view ofthe spindle and ring at the juncture thereof. Fig. 3 isa section of the det-ail shown in Fig. 2.

The ring A ot' the damper consists of two parts, C and D, as in Fig. 1,the said parts being each provided with recesses E at diametrieally-opposite points, and on each side ot' which recesses areother recesses, F. The

provided willi side wings or tlanges, G,whieh, when the said spindlesare secured between the two parts of the ring. rest in the recesses Fandprevent the spindles from turning in their seats. The outer ends ofthespindles bcyond the pipe, are formed into or provided with fiat heads,which serve as a convenient means of manipulating the damper, one orboth the said spindles beingso formed. Plates l, having ovcrhanging edgeflanges and being also provided with legs K, cast on them, are securedon opposite sides of the ring by bolts or other suitable means, the saidbolts or fast- (No model.)

enings passing through the ends of the legs K, which are bent at an angie for the purpose, the bolts serving in the construction shown in Fig.l to also fasten together the two parts of the ring.

ln order to make two legs seeurel y and iirml y support the plate onwhich they are formed, they are arranged diametrically opposite, and onthe plate are cast lugs L, which are either 'formed long enough to reston the ring or to of the damper is cheapened and the number of' pieceslessened, while the advantages ofthe form of damper are retained.

I'do not limit myself to the exact construe tion shown and described,as-the saine may be varied without departing from the spirit ot' myinvention.

Having thus described my invention, what I claim is- A damper consistingof a ring formed ot'two parts having diainetrically-opposite recesses,plates oil opposite sides of the ring, and spindles or trunnions havingwings or iianges thereon engaging in the recesses in the rings,substantially as and for the purpose specified.

In testimony whereof l at'tix my signature in presence of two witnesses.
